One symbol which continues to remain popular is the lower case Greek letter lambda.
The symbol was originally chosen by the Gay Activists Alliance of New York in 1970. The GAA was a group which broke away from the larger Gay Liberation Front at the end of 1969, only six months after it's foundation in response to the Stonewall Riots.
While the GLF wanted to work side by side with the black and women's liberation movements to gain unity and acceptance, the GAA wanted to focus their efforts more concisely on only Gay and Lesbian issues.
Because of its official adoption by the GAA, which sponsored public events for the gay community, the lambda soon became a quick way for the members of the gay community to identify each other. The reasoning was that the lambda would easily be mistaken for a college fraternity symbol and ignored by the majority of the population.
Eventually though, the GAA headquarters was torched by an arsonist, destroying not only the building but all of the organization's records, and the movement never recovered from the loss. The symbol, however, lived on.
Whatever the lambda meant or means today, it's everywhere. Even though at one time it acquired a strictly male connotation, it is used by both gays and lesbians today. Back in December of 1974, the lambda was officially declared the international symbol for gay and lesbian rights by the International Gay Rights Congress in Edinburgh, Scotland.
The lowercase Greek letter lambda carries several meanings. First of all, it represents scales, and thus balance. The Greeks considered balance to be the constant adjustment necessary to keep opposing forces from overcoming each other. The hook at the bottom of the right leg of the lambda represents the action required to reach and maintain a balance.
To the Spartans, the lambda meant unity. They felt that society should never infringe on anyone's individuality and freedom. The Romans adopted the letter to represent "the light of knowledge shed into the darkness of ignorance." Finally, in physics the symbol designates and energy change.
Thus the lambda, with all its meanings, is an especially apt symbol for the gay liberation movement, which energetically seeks a balance in society and which strives through enlightenment to secure equal rights for homosexual people.
